CAR-COUPLING.

To all whom it may concern Be it known that I, ARTILUR J. Baznmn', a.citizen of the United States, and a resident of Cleveland, Guyahogacounty, Ohio, have invented a new and useful Car-Coupler, of which thefollowing is a full, clear, and exact description, reference being badto the accompanying drawings, forming part of this specification, inwhich Figurel is a front elevation of a car coupler constructed inaccordance with my invention, and provided with a lock-lifting mechanismoperated from above; Fig. 2 is a vertical longitudinal section of thecoupler; Fig. 3 is a detail side elevation; and Fig. t an edge view ofthe lifting link; Figs. 5 and (3 are similar views of the locking device for the lock; Fig. 7 is a detail view of the lock; and Fig. 8 is avertical cross section through the coupler head showing the attachmentof the parts to the lock.

Referring to the top opening coupler shown in l to S, 2 represents thecou pler head and 3 is the knuckle of the coupler; and l; is the lockingand opening piece of the coupler, which is preferably of angled form, asshown in detail in Fig. 7, having a limiting-head 4i and a member t.which fits back of the tail of the knuckle and is adapted to open thesame. The locking and opening piece has also an intermediate memberhaving preferably a notch or recess t" adapt ed to engage the head ofthe coupler and to tip thereon for the purpose of swinging the knuckleopen, as illustrated in Fig. 8. The lower link 5 of the lifting chain isconnected with an eye (3 formed on or cast integral with the top of thelocking member a and this link 5 has at its upper end an elongated hole5, a forward projection 5" and a rear projection 5. Between these is anintermediate recess 5.

The upper link 7 of the chain within the coupler head is preferably offork or clevis form, and is attached to the lower link by means of a pin7 secured with a suitable cotter. This link has a recess between twovertical walls 7 and 7 divided by an intermediate rib 7 and at the topof the link 7 is an eye 7 through which extends the arm of thetmcoupling rod 8. The link 7 extends through a hole at the top of thecoupler head and is preferably made larger at its upper portion, ofsuitable size to fill this hole Specification of Letters Patent.

when the link is in its lo\\"ermost position so as to exclude dirt fromthe coupler.

When it is desired to lift the lock, the lifting rod 8 is operated bymeans of a lever handle 9 so as to lift the links 7 and 5, the link 5fitting within the fork of the link 7 and being held thereto by a pin 7which passes through the elongated hole 5. The lifting of the linkspulls them into alincment and draws the link 5 into line with the holein the coupler head and enables it to pass freely through the hole.\Vhen, however, the lifting rod is released so as to permit the linksand the lock to descend, the elongated hole 5 will permit the pin 7" todrop downwardly with the link 7, so that the wall 7" of the link 7 willengage the link at the top of the projection 5", and as this point ofengagement is back of the atlachnu-nt of the link 5 to the lock at (S,the link 5 will be caused to move lmckward at its upper end so as tobring the inner side of the projection 5* into engagement with themiddle rib 7", thus holding the link 5 from further backward movement.The projection 5", being thus brought beneath the upper wall of thecoupler head, is held posilivel from rising, and any tendency of thelock to jump or creep upwardly is resisted. it, however does not preventthe free lifting of the links and of the lock, for as soon as the link 7is lifted it will draw the link 5 into alinement with it and thus freethe projection 5" from engagement with the coupler head, taking it outof the path thereof. As the middle rib 7 of the link 7 is between theprojections .1" and 5" of the lower link, the movement of the two linksrelatively to one another is limited and the upper link is kept in asubstantially upright position when the lock is raised.

This device may be modilied by applying it to looks of otherdescriptions, and it may be operated by lifting mechanism other than thekind shown in the Fig. l of the draw ings.

I, claim:

1. A coupler having a swinging knuckle, a lock engaging the knnckletailand movable independently of the knuckle, the top of the lock beingbelow the top wall of the coupler cavity, leaving a space between saidwall and lock when the knuckle is locked, and a lock lifting devicecomprising a plurality of jointed members extending through the space inthe upper part of the head and through a hole in the top Wall of thecoupler head, said members being arranged to cause the lower member tomove laterally by gravity under a stop shoulder on the coupler head toprevent creeping of the lock, and the upper member having an enlargementarranged to seat against the rim of the top hole in the coupler headwhen the knuckle is locked, the jointed members having a slottedconnection and being angled therein and the lower member being held inan inclined position to engage the stop on the coupler head, saidmembers also having co-acting portions which limit their angularmovement in both directions.

2. In a car coupler, a lifting link adapted to have a locking engagementwith the upper wall of a coupler head, a clevis pivoted to said link andhaving a slot to receive the upper portion of the link, said slot havinga stop portion, and a shoulder on the link arranged to be engaged bysaid stop to limit the backward movement of the upper end of the linkunder the upper wall of the coupler; substantially as described.

In testimony whereof, I have hereunto set my hand.
